Title: Rapid fault detection and recovery for internet protocol telephony
Inventor: KAROL MARK JOHN
IPC: H04L69/40
Filed: 2005-05-27
Granted: 2011-03-29
Abstract: Techniques for performing rapid fault detection and recovery in communication networks are disclosed. For example, in one aspect of the invention, a technique for detecting one or more conditions in a communication network comprises the following steps/operations. One or more keep-alive packets are transmitted from a source node in the communication network to a destination node in the communication network over two or more paths between the source node and the destination node, wherein the two or more paths are at least partially disjoint. Upon receipt of the one or more keep-alive packets at the destination node via the two or more paths, at least one quality measure is computed at the destination node for each of the two or more paths, the at least one quality measure being indicative of one or more conditions in the communication network. While not limited thereto, the invention is particularly well-suited to Internet Protocol (IP) telephony networks, particularly those that provide Voice over IP (VoIP) applications.

Title: Single-use long-life faucet-mounted water filtration devices
Inventor: RIZZARI ROBERT
IPC: B01D27/00
Filed: 2004-07-01
Granted: 2009-01-06
Abstract: Single-use long-life faucet mounted water filtration devices (100) are disclosed. A bathroom water filtration device having two outlets (106, 107) for water is disclosed. Additionally, a fountain head (119) is included for use in the bathroom water filtration device. The water filtration device is of unibody construction formed by ultrasonically welding certain parts thereof together. Since the devices disclosed are disposable, no filter replacement or other maintenance is performed. A gate (118), magnet (117), sensor (135) and electronics (112) provide an indication of filter performance enabling disposal of the water filtration device and installation of a new device. A  kitchen water filtration device is larger than the bathroom device. Both the kitchen and bathroom water filtration devices are small and are mounted behind the faucet connection so as to facilitate full utilization of the sink or wash basin.

Title: Medical needle device with winged shield
Inventor: MORIWAKI KUNIHARU
IPC: A61M25/06
Filed: 2004-03-22
Granted: 2010-09-21
Abstract: A medical needle device has a winged shield (4) with a pair of wings (5, 6) at the fore-end side of a shield tube (4a) with a substantially circular-tube shape, a hub (2) axially movably inserted in the cavity of the shield tube, and a needle tube (1) installed at the fore-end of the hub. An infusion tube (3) can be connected to the rear end of the hub, and the fore-end of the needle tube can be received in the cavity of the shield tube. At least part in the axial direction of the sealed tube is bendable with the needle tube, projecting from the fore-end of the needle tube, engaged to the sealed tube.  This makes it possible that the shield tube, even with the wings, is bent to a curve and the bending is made at a position sufficiently close to the needle tube.

Title: Horizontal injection molding machine with turning device
Inventor: LICHTINGER PETER
IPC: B29C45/17
Filed: 2004-10-08
Granted: 2011-12-20
Abstract: Conventional horizontal injection molding machines comprise a stationary turning device for turning the half-molds about a vertical axis and two mold platens that are mounted on a machine bed for movement along a longitudinal machine axis.  These conventional injection molding machines were problematic in that the size of the molded parts produced in these injection molding machines was limited since the turning device was configured with a rigid frame through which tie bars of the injection molding machine were guided. The aim of the invention is therefore to provide a horizontal injection molding machine that can be used in large installations with large-size half-molds and that allows for a rotary mode as well as a reversible four-step mode of operation. The horizontal injection molding machine should also be suitable in a clean-room environment. For this purpose, the turning device (26) comprises a base (28) and a turntable (30) rotatably mounted on the base (28). The base (28) is stationarily arranged on a machine bed (2) between the two moving mold platens (6, 8) and the turning device (26) is dissociated from the tie bars (14).

Abstract: Un manchon d'injection de fluide sous pression (10) destiné à être monté sur le corps principal (1) d'un boulon de blocage est constitué d'une saillie (11) cylindrique de diamètre élevé et d'un support de rondelle (12) de faible diamètre, le diamètre externe du support de rondelle (12) étant inférieur au diamètre du trou d'une rondelle (6). Il est souhaitable que la saillie (11) de diamètre élevé et que le support de rondelle (12) possèdent un diamètre interne égal. Lorsque le corps principal (1) du boulon de blocage est noyé dans un substrat rocheux ou dans le sol, la rondelle (6) repose sur le bord d'un trou d'insertion de boulon de blocage, tandis que le support de rondelle (12) s'étend dans le trou d'insertion de boulon de blocage. Par conséquent, la rondelle (6) et la saillie (11) de diamètre élevé sont les seuls éléments qui font saillie à partir d'une couche de béton pulvérisé disposée sur le substrat rocheux ou le sol. La hauteur de la saillie est restreinte, ce qui facilite la mise en place du béton de revêtement et permet donc un travail de renforcement de grande fiabilité.
